RAILWAY-FROG.

FJPECEFICATION forming part of Letters Patent No. 332,980, datedDecember 22, 1885.

Application filed October 8, 1885. Serial No. 179,355.

To all whom it may concern.-

Be it known that I, FREDRIO O. WEIR, of Cincinnati, in the county ofHamilton and State of Ohio, have invented certain new and usefulImprovements in Railway -Frogs, of which the following is aspecification.

My invention relates to an improvement in railway frogs and crossings.

The object of my invention is to provide a better means for connectingthe parts together and supporting the rails in a cheaper and bettermanner than by the methods hitherto employed.

Another object of my invention is to employ brace-plates which, togetherwith the rails, form an arch or a truss support for the pointrails.

Another object of my invention is to employ these brace-plates forfilling and spacing plates, which, in connection with the wing-rails,form an arch or truss support to the point-rails.

Another object of my invention is to employ through-bolts in connectionwith the supporting straps and plates, which will firmly unite and holdall the rails in a cheaper and better manner than hitherto employed, allof which will be fully set forth in the description of the accompanyingdrawings, making a part of this specification, in which- Fignre l is atop plan View of my improvement with section broken off to show theparts; Fig. 2, a section on line a: m, Fig. 1; Fig.3, a perspective viewof one of the brace or supporting plates. and Fig. 4 a perspective viewof a modified form of filling-blocks.

A represents the short and B the long point of an ordinary railway-frog.These parts may be swaged, jointed, or fitted together in any well-knownmanner. The short point-rail is shown in Fig. 2 as swaged up, so as torest upon the flange of the long point-rail, and this is the preferredform of uniting the parts.

0 D represent wing-rails, which are bent to conform to the desired angleto serve as guards and main-track rails in the usual manner.

1 represents channel-shaped clamp-bars; 2 represents the flanges orsides of the same. The base of the rails rests upon these clampbars.

3 represents filling blocks which abut against the wing-rails on oneside and against the flanges of the clamp on the opposite side.

(No model.)

E represents brace-plates. Fig. 3 shows the preferred form ofconstruction. One edge of these plates is shaped to fit against the headand web of the rail, as shown in Fig. 2, and the opposite edge fitsagainst the web and flange of the wing-rail, occupying the inclined ordiagonal position shown therein.

4 represents bosses or sleeves, preferably cast integral with theseplates, through which sleeves holes are pierced sufficiently large toreceive the through-bolt 5. These holes should be enough larger than thebolts to prevent the down-thrust upon the same, to obviate all clangerof breaking or cutting off the bolts.

6 represents a nutlock between the nut and flange 2, so as to preventthe nut from turning backward.

The braceplates E, together with the web, flange, head. and clamp-boltform a truss or arch support for the rails, and the filling-blocks 3,clamps 1, bolt 5, and brace-plates E form a very firm support for thewing rails D against the outward thrust by the impact of the carwheels.

This form of constructing a frog employs a minimum amount of metal to agreat advantage, and yet has sufficient elasticity to insure thedurability of the structure.

I have shown the braceplates E made of one piece and three clamps, 1, tobind the sections of the frog together.

It is evident that the parts E may be made in sections without changingthe principle of construction herein. So, also, a single clamp orchannel bar, 1, of considerable length could be employed as a substitutefor three, and still attain the principal results of my invention.

1 have also shown the base of the point-rails to be slightly above theclamp-bars. This is the preferred form of construction, as it gives anincreased amount of elasticity, takes up lost motion, and insures theimpinging of the arched structure for lateral support.

In Fig. 4 and in the broken sections of Fig. 1 the filling-blocks 3 areshown of wedge shape, with a slotted or elongated bolt-hole. This is forthe purpose of allowing the filling-block to be used as a key to tightenthe clamp and structure.

I claim- 1. In combination with the wing-rail of a. frog, an inclinedsupport, E, serving as aspacing and supporting'plate between the wingand 4.
